For months now the rear speakers and sub havent worked so i finally ordered the stereo keys and got them today. I did the research so they're definately the right ones. Ok so i went to put all 4 in and only 2 clicked in place, the top left and the bottom right. The other 2 wouldnt lock on but there was resistance so i tried to pull it out and prise it a little bit, anyway it half came out but no luck with the full thing. So after giving up the 2 good keys are stuck in and the stereo wont fully go back in and now it wont work properly, it kind of comes on but i have no screen or any control! is cutting it out my only option?
